Introduction: What is waste? What kind of wastes do we produce? Why is waste an issue?

Unsustainable Consumption. The Wasteful ‘Economy’ Climate change? What can we do about it?

What is waste?What is waste? There are complex legal definitions (EU):

Holders intent to discard? Is it hazardous? Does it have a market for its re-use? Evolving – When does it cease to be waste?

Essentially any matter in the wrong place at the wrong time! Single point or multi point (diffuse). Solid, liquid, gaseous. Natural or Xenobiotic. A ubiquitous and inevitable consequence of human activity. Inextricably linked to patterns of production and consumption. Closely related to ‘wealth’.

What kind of wastes do we produce?

What kind of wastes do we produce?

Industrial by products. (solid, liquid and gaseous) Pesticides. (escaped) Fertilizers. (escaped) Sewage wastes (domestic and industrial). Natural materials (food by products, forestry brash). By products of consumption. (plastics, paper, metals,

organics, pharmaceuticals – MSW) Construction and demolition wastes. Automotive (cars, tyres, exhausts, oils) Agricultural.

Why is waste an issue? (1)Why is waste an issue? (1)

Impact on human health: Pathogens (sewage, landfill leachates,

agricultural wastes). Heavy metals (Pb, Hg, Cr et al…) Persistent organic pollutants (POP’s) – PCBs’,

PAHs’. Air, water, food, skin contact. Infective, Toxic, Mutagenic, Carcinogenic.

Why is waste an issue? (2)Why is waste an issue? (2)

Economic loss: Contaminated land (heavy metals,

hydrocarbons). Polluted water courses (oil, eutrophication). Contaminated food sources (TBTO). Human health impacts.

Why is waste an issue? (3)Why is waste an issue? (3)

Impact on the Environment: Climate change – carbon effects. Water, land and air quality. Organisms (fish, birds, plant life etc) - Effects on

biodiversity. Ecosystem damage – acid rain.

The Root problem – Unsustainable Consumption

The Root problem – Unsustainable Consumption

Per capita consumption continues to increase as global GDP grows (3-4%) outstripping population growth (1-2%).

Resource consumption per capita and per unit GDP declining but overall resource consumption and waste production continues to grow due to population and economic growth.

Richest 20% account for over 80% of global consumption. 6,400 kgoe per capita. 1,600 litres of fuel per capita US.

Poorest 20% account for less that 2% of global consumption. 620 kgoe per capita. 31 litres of fuel per capita sub

Saharan Africa. Global forested area reduced from 12 sqkm – 7sqkm (1970-

1999). Global fish stocks under pressure. Oil, water, land and natural resource wars. ‘Filling a hole what needs to be made whole!’.

SUN

..and warms the earth.

..most escapes to outer spaceand cools the earth...

Infra-red radiationis given off by the earth...

…but some IR is trapped by some gases in the air, thus reducing the cooling.

IMPACTS OF CLIMATE CHANGE

1900

2000

“Insurance companies estimate that the bill for severe weather in the 1990s worldwide was $480 billion, with the economic… losses over that period increasing by a factor of 8… If these rates are projected into the future in comparison to a standard growth in GDP of 3% per year, by 2065, the world would become bankrupt, as damages would outstrip global earnings.”

Simon Retallack, The Ecologist Report, November 2001

HOW CAN WE REDUCE CO2 EMISSIONS?HOW CAN WE REDUCE CO2 EMISSIONS?

Reduce emissions - Use less energy

insulate homes, businesses and factories

less polluting transport; travel less

Combined Heat and Power

Reduce emissions - Generate energy without emissions of CO2

renewable energy (wind, solar..)

nuclear power

Sequestrate carbon – soils, seas, forests, mechanical.

Reduce landfill of bio-degradables.

Adapt.

What can we do? (1)What can we do? (1)

The most urgent need: To close the gap between developed and developing countries.

Ensure waste collection services are available to as large a part of the world’s population as possible and to raise the quality of landfill sites.

Develop policy and economic support frameworks for the waste hierarchy.

Recognise wastes as a resource. Stop the increasing export of environmental

problems to the developing countries.

What can we do? (2)What can we do? (2) Reduce consumption.

Education – why do we consume so much? Global equity.

Improve production: Producer responsibility. Raw material taxes. Product taxes. Disposal bans and taxes. De-materialise - Decouple waste from GDP. Integrated Product Policy.

Technology and knowledge transfer.

What can we do? (3)What can we do? (3)

Develop national, economic block and global resource management plans (EU Thematic Strategy on Natural Resource Use).

Address the increasing deficit of human ‘happiness’ that is one of the driving forces in unnecessary consumption.

The Christian PerspectiveThe Christian Perspective

‘The Earth is the Lord’s and all that is in it’. It was our inheritance – this implies stewardship. Will judgement in part relate to how we have

treated God’s creation? Revelation 18 and 19.
